Abstract

The contact between a touchdown sensor and an asperity on a disk is investigated using finite element analysis. The touchdown sensor is embedded in the area of the thermal protrusion of a thermal flying-height control (TFC) slider. A transient thermo-elastic-plastic finite element contact model is developed to simulate the temperature rise of the touchdown sensor due to frictional heating.
